I've committed detailed results of this detector's performance on the test set to this PR.

On the RAID dataset as a whole (aggregated across all generation models, domains, decoding strategies, repetition penalties, and adversarial attacks), it achieved an AUROC of 96.44 and a TPR of 89.32% at FPR=5% and 80.87% at FPR=1%.
Without adversarial attacks, it achieved AUROC of 97.46 and a TPR of 92.31% at FPR=5% and 84.80% at FPR=1%.

If all looks well, a maintainer will come by soon to merge this PR and your entry/entries will appear on the leaderboard. If you need to make any changes, feel free to push new commits to this PR. Thanks for submitting to RAID!

Hi RAID maintainers — if the eval results above look good (AUROC 96.44 with adversarial / 97.46 without; TPR@5% 89.32 with / 92.31 without; TPR@1% 80.87 with / 84.80 without), I'd appreciate a merge so this baseline is locked in on the leaderboard before I push the v18 successor PR later today.

Thanks!
